|
|
* This test tool verifies that PIN asserts that trace re-generation is equal
|
|
* to the original trace generation.
|
|
* When PIN generates a trace in the code cache, it does not generate the
|
|
* meta-data for that trace (App instructions vs. instrumentation code vs. spill/fill code).
|
|
* This meta-data is created only in case of an exception, when PIN needs to figure out what
|
|
* code caused the exception, by re-generating the trace. If the instrumentation scheme changes
|
|
* between the first and second trace generation, the results of the exception analysis are bogus.
